Shutting down the guest OS Centos 6 (I used 6.2) results in a shutdown of the OS but the actual VM does not shutdown.
# shutdown -h 0
Tried to activate the ACPI module in the kernel by editing the grub.conf file and this worked!
# vi /boot/grub/grub.conf
acpi=off to acpi =on
After a reboout try a
shutdown -h 0 again.
ACPI (Advanced Configuration and Power Interface) is an industry specification for the efficient handling of power consumption of peripherals such as hard drives.
The poweroff option is highly dependent on the system hardware in use. Specifically, certain hardware components such as the BIOS, APM (advanced power management), and ACPI (advanced configuration and power interface) must be able to interact with the system kernel.
